Specification of Letters Patent.

Patented Oct. 12, 1915.

Application filed December 28,1914. Serial No. 879,302.

relates more particularly to a pneumatic cushion for the use of convalescents.

The primary object of the invention is to provide a cushion which has improved means for preventing slipping on the mattress or bed. I

Further, the invention resides in the provision of a cushionof the type set forth which is of simple and economical construction, and which is formed so as to resist wear and to afford a comfortable seat for the invalid.

In the drawings Figure 1 is a side elevation of a bedshowing the invention in usethereon. Fig. 2 is a top plan view ofthe invention, the securing straps being broken away, and Fig. 3 is a section on the line 33 of Fig. 2.

In proceeding in accordance with the present invention the cushion is formed of a number of sections 1, which sections are provided with walls 2 perforated at 3 and having top and bottom extensions 4 and 5 respectively, thefree portions of which are secured at 6 to the tops and bottoms of the adjacent sections. For the purpose of effectively sealing the ointsformed at 6, longitudinal stays 7 are provided, which stays are superimposed upon the joints 6 and extend on opposite sides of the'latter so as to completely cover the joints 6. The stays also serve to reinforce the cushion, and strengthen same.

At the rear of thecushion an opening 8' 12, which latter seal the tops andbottoms of the sections 1 adjacent to the opening, as depicted in Fig. 3. The rear of the cushion terminates in a flap l3,the latter being connected to end closures 14 which'are cemented to the ends of the sections 1. For the purpose of holding the cushion on a bed or mattress without slipping thereof, a pair of retaining straps of rubber 15 are provided, which straps are adapted to be tied to the head of the bed asshown in Fig. 1 of the drawings. Each succeeding section 1, from the flap 13, is of greater height than the next preceding section whereby the top and bottom of the cushion diverge from the flap.

The walls 2 of the sections 1 serve to limit the extent of inflation of the cushion as a whole, and act as braces in addition. The purpose of the opening or cut-out portion is to cause the cushion to rise more or less on the sides I of theperson, or at the ends of the cushion, so that the cushion will more firmly engage the bed or mattress and thus be held against slipping, I

Having thus described my invention, I claim as new and desire to secure by Letters Patent r An invalid cushion comprising a nonsinflatable flap adapted to rest on a bed, anchoring means onone side thereof, and an inflatablecushion body consisting of a series of sections of U-crosssection, the forward section of the series having its free side edges secured to the flap opposite from the anchoring means and each succeeding sec tion being of greater height than the preceding section and having its free side edges secured to the next preceding section at a point adjacent the wall connecting the sides of the latter section, the connecting wall of each the ends of the series of sections and the flap, said cushion being provided with an cent sections.

In testimony whereof I have signed my opening bounded by'the flap and the adjaname to this specification in the presence of two subscribing witnesses.
